Application filed February 24, 1909, Serial No. 479,737. Renewed October 23, 1916.

To all whom it may concern:

Be it known that I, WILLIAM C. SCHMIDT, citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia,have invented certain new and useful Improvements in Indicating- Bottles; and I do hereby declare the following to be a full, clear, and exact description' of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in certain new and useful improvements in indicating bottles. The object of my invention is to provide a closure for bottles intended to contain va rions kinds of liquids, so constructed as to permit the contents of a bottle to be freely poured therefrom but which will indicate with certainty any attempt to insert liquid into the bottle after it has once been emptied or partially emptied of its original contents.

To this end I provide my improved bottle with an indicating device having a part which is adapted tobe totally or partially destroyed, disintegrated or removed by chemical action, which is set up by liquid coming in contact with a part impregnated with chemicals, thereby carrying with it a word or indication or symbol, showing the contents to be original and on dissolution, displaying a word or other indication showing the bottle to be refilled.

In order that the invention may be understood, I have illustrated it in the accompanying drawings, in which I have shown a form of bottle which I may employ, a closure for the same and also slight modifications thereof.

In the drawings,

Figure l is a vertical sectional view ofone form of my improved bottle and closure.

Fig. 2 is a similar view of a modification of my invention, with the stopper retracted.

Fig. 3 is a similar view of a further modiication of my invention.

Fig. 4 is a top plan view of the closure or disk C on lines z-z of Fig. 2.

Fig. 5 is a top plan View of the member B on lines y-fy of Fig. 2.

Fig. 6 is a similar view of the closure'or disk C on lines :z2-m of Fig. 3.

Fig. 7 is a side view of the bottle neck when filled and closed ready for use.

Fig. 8 is a similar view showing the bottle open and that an attempt has been made to refill it.

Specification of Letters Patent.

Patented June 5, 1917.

Serial No. 127,313.

Similar letters of reference indicate identical parts throughout.

A represents the neck portion of my improved bottle provided with my invention,

and having internal screw threads a as shown. B is a member forming part of the gage the screw threads in the neck of the bottle.

F is a washer of cork or other suitable material seated in arecess in thepneck of the bottle and below the threaded portion thereof, to prevent the contents of the bottle from passing the threads and entering the recess c, by tightly screwing B against the washer F. At the top of the member B is a disk or flange C provided with serrations c at its outer edge. This disk is of such diameter in cross section as to leave a small space between its circumference and the inner surface of the neck of the bottle, and a deeper recess o is provided between the disk or flange and the screw threaded portion of the member B so that a greater space is left between the inner surface of the neck of the bottle and the outer surface of the recessed portion of the member B, than between the circumference of the disk or flange C and 'the bottle neck, thus providing a cup like receptacle for the indicator. Around the disk or flange C, I place a band or ribbon E of some absorbent material such as blotting paper, substantially l: shaped to form a baffle above and below the disk or flange C, as will hereafter appear, and in the recess c I place a. second piece or band of absorbent material similarly shaped as at E in the drawings, and within the second baffle I place the indicator Gr.

K in Figs. l and 2 is a cylinder and is a part of member B, being connected with it by ribs which form channels e. The upper part of the cylinder K is threaded at c2 to receive the shank c3 of the stopper D. The lower end ofthe cylinder K is closed by means of a stopper of suitable material, as a cork 7s to prevent the outiiowing liquid from entering the said cylinder.

The indicator G consists of a ribbon or strip of any suitable material such as paper,

'fabric tape, etc., with an indication of fraud thereon, such as the word reiillech coated with a mixture of non-transparent sub stances, and chemicals as Whiting mixed with a non-hygroscopic substance, as a carllO bonate and preferably bicarbonate of soda which conceals the fraud indication.

On this coating appears by printing, stamping or otherwise any desiredword or words, marks or symbols indicating originality of the contents, such for example as 'the word Original which indications are to the indicator without the use of a strip of absorbent material. f

Then an attempt is made to refill the bottle, the inflowing liquid will be forced into contact with the two ribbons and a chemical' and mechanical action ensues which destroys the coating on which the indication Y of originality appears and the said coating is chemically removed carrying with it the indication of originality and displaying the indication of fraud. The removal of the indication of originality and coating is mechanically accelerated by the carbonic acid gas formed by the action of the chemicals.

used.

It is obvious that instead of having two .separate'ribbons or strips, a single ribbon or strip may be used, one side being coated with 'a non-hygroscopic carbonate and the.

other rside impregnated with a suitable acid.

It is also perfectly obvious that fraud indications, such as the word Itefllled may be coated as heretofore described, and no further indication printed on'the coating, the plain coating being the evidence of originality. In this case ther attempt to refill .the bottle would destroy the coatingas heretofore described, and disclose the fraud indication, or the plain ribbon might be the indication of fraud, coated as described, with the symbol of originality thereon. In this case anv attempt to refill the bottle would destroy the coating and the symbol of originalityfleaving the plain ribbon to indicate fraud. Many variations of my improved indicating ribbon may occur in the practi-V cal application of my invention.

In Figs. l and 2 the member B is so formed that by means of ribs, passages e are provided for the outlety of liquid from the bottle.` Y

The stopper D may be of any desired form, the oneJ shown consisting of a main portionv D provided with the screwthreaded shank c3 which engages the screw threaded opening c2 of the part C in Fig. 3 or the upper part of K in Figs. l and 2, Thestopper is provided with cored washersy which 'close' the mouth of the bottle and channels by screwing the stopper shank c3 into the opening 02.

A ring Z ,is providedV for the shank after itis in place toprevent the entire withdrawal of the stopper but allowing the same to be unscrewed a sufficient distance to open the mouth of the bottle and passages @.for the purpose` of decanting the contents of the bottle. A

In Fig. l, the parts Band C are made integral and the stopper shank is inserted through the opening c2 `and keyed in place by means of the ring CZ.V

Theindicating device as described, is then placed in position and also the baffles of absorbent material,y as shown and the part B then screwed into the neck of the bottle and permanently.secured by means of ce ment against the washer F.V The bottle is Y then ready for the market.

In decanting the contents, in case of any backward' drip when a portion only of the contents `is poured out, such dripping is caught by a plurality ofprotectingbaffles and the indicating ribbon is thus protected, but'when an effort is made torefill the bottle, the incoming liquid will pass the baffles and will come in 'contact with the indicating ribbon or ribbons setting up the chemical and mechanical action heretofore described, and it will become apparent to the user that the bottle has been refilled.

Theconst-ruction shown in Fig. Y2 is the saine as that showny in Fig. 1, kexcept that the parts B and Cv are made separate, the disk C being permanently screwed to the part B .as atV H. The lower'poitiony of the part B is alsoprovided with an annular partition I of some transparent substance, such as glass or other suitable material,

rforming two chambers, one for eachof the two ribbons heretofore described. YThis partition is in effect a baffle and acts in the place Vof the lower baffle already described.

The indicating ribbon coated with the nonhygroscopic carbonate, is placed in the outer chamber and the ribbon impregnated with i the acid is placed in the innerV chamber, thereby preventing any chemical action until enough liquidV is forced' into thc outer chamber to overflow the partition I when the chemical action heretoforey described will be set up. f

Fig. 3 is identical with Fig. 2 except that the cylindrical portion K ofthe part B is omitted, the threads being formed in the ribs L of the disk, Fig. 6, to engage the stem Vc3 of the stopper D. In this view the'indieating ribbon is shown as a lsingle ribbon or s twoV ribbons back to back, the outer surface orv ribbon bearing the fraud indication and coating of non-hygroscopic substance, and

the inner'surface or ribbon being impregnated with acid. InV this view I have also shown a conical Vvalver X whichis loosely vplaced in the narrowed portion-of the neck of the bottle. This valve when the bottle is inverted will permit the ready outflow of the contents of the bottle, but Will act as an additional deterrent to refilling the bottle, and in case an attempt is made to force liquid into the bottle the valife will close the bottle and cause the liquid to iill the recess in which the indicator is located.

This indicating ribbon or double ribbon is placed in the inner chamber. lt is obvious that the partition I will protect the ribbon from backward drippings and no absorbent baffles will be necessary, but that in an attempt to refill the bottle, the outer chamber will quickly overflowv the'partition l, and the liquid entering tne inner chamber will cause the cliemicaland mechanical action heretofore described, to take place and show the bottle to be refilled.

. One form of ribbon which l have conteniplated using consists in a strip of suitable material in'ipre'nated With citric acid and having characters of originality thereon formed preferably of bi-carbonate of soda. These characters are chemically removed by the citric acidk in solution with the iniiovving liquid.
